Abstract
Description
- This invention generally relates to a bicycle front derailleur. More specifically, the present invention relates to a bicycle front derailleur in which a width of a chain receiving slot can be adjusted.
- Generally, a front derailleur is mounted to the bicycle frame adjacent to the front sprockets to shift a chain laterally between the front sprockets. A front derailleur includes a fixed or base member non-movably secured to the bicycle frame, and a movable member with a chain guide that is movably supported relative to the fixed member to move between at least two lateral shift positions. Typically, a linkage assembly is coupled between the fixed member and the movable member in order to movably support the movable member with the chain guide. The chain guide has a pair of cage plates or guide plates arranged to selectively contact and move the chain between the front sprockets. The chain guide is usually moved relative to the base member by pulling and/or releasing a shifter control cable that is coupled between a shifter and the front derailleur. The control cable is often connected to one of the pivotal links to apply a torque thereto in order to move the chain guide between an extended position and a retracted position. One example of this type of a conventional front derailleur is disclosed in
U.S. Patent Publication No. 2007/0191158 . More recently, front derailleurs have been developed the use other types of arrangements (e.g. an electric motor arrangement, a hydraulic arrangement, etc.) for moving the movable member between an extended position and a retracted position. - One aspect is to provide a bicycle front derailleur in which a width of a chain receiving slot can be adjusted.
- In accordance with one aspect of the present disclosure, a bicycle front derailleur is basically provided with a base member and a movable member. The base member includes a bicycle mounting portion. The movable member is movably supported to the base member between a retracted position and an extended position relative to the base member. The movable member includes a first guide plate having a first inner surface and a second guide plate having a second inner surface. The first and second inner surfaces face each other to form a chain receiving slot therebetween. The second guide plate includes an adjustable guide member that is arranged at the chain receiving slot to move between at least two different positions relative to the second guide plate.

Thefirst guide plate 41, thesecond guide plate 42 and the first connectingportion 43 are formed as a one-piece, unitary member. The second connectingportion 44 is also formed preferably formed as a one-piece, unitary member with thesecond guide plate 42. The second connectingportion 44 is attached to thefirst guide plate 41 by a fastener 46 (e.g., a rivet). Thefirst guide plate 41 has a firstinner surface 41a for contacting and laterally shifting the bicycle chain such that the bicycle chain moves in an outward direction with respect to thebicycle frame 10 between the chain rings 18 and 20. Similarly, thesecond guide plate 42 has a secondinner surface 42a for contacting and laterally shifting the bicycle chain such that the bicycle chain moves in an inward direction with respect to thebicycle frame 10 between the chain rings 18 and 20. The first and secondinner surfaces chain receiving slot 48 therebetween. - As best seen in
Figures 3 to 7 , thesecond guide plate 42 is provided with anadjustment structure 50 for adjusting a minimum effective width of thechain receiving slot 48 between the first and secondinner surfaces adjustment structure 50 is used to vary the minimum effective width of thechain receiving slot 48 as measured perpendicularly between first and secondinner surfaces adjustment structure 50 is used for contacting and laterally shifting a bicycle chain during a downshifting operation of the chain from thelarger chain ring 18 to thesmaller chain ring 20. The firstinner surface 41 a is disposed between thebase member 26 and the secondinner surface 42a. - The
adjustment structure 50 basically includes anadjustable guide member 52 that is arranged at thechain receiving slot 48. Theadjustment structure 50 further includes anadjustment member 54 that is movably disposed between thesecond guide plate 42 and theadjustable guide member 52 such that movement of theadjustment member 54 selectively moves theadjustable guide member 52 relative to thesecond guide plate 42.

Further, thesupport structure 56 includes aprevention flange 56b to prevent large debris from entering into a space between thesecond guide plate 42 and theadjustable guide member 52. Also as shown by a broken line inFigure 10 , anadditional prevention flange 56c can be optionally provided. Theadditional prevention flange 56c is also effective to prevent large debris from entering into a space between thesecond guide plate 42 and theadjustable guide member 52. - The
adjustable guide member 52 becomes the effective inner surface of thesecond guide plate 42. Theadjustable guide member 52 is primarily arranged in an area of thesecond guide plate 42 that is used for downshifting a chain from thelarger chain ring 18 to thesmaller chain ring 20. Thus, theadjustable guide member 52 is primarily located along a front half of the secondinner surface 42a of thesecond guide plate 42. In this way, theadjustable guide member 52 is used to contact and laterally shift a bicycle chain such that the bicycle chain moves in an inward direction with respect to thebicycle frame 10 from thechain ring 18 to thechain ring 20. - Referring to
Figures 4 ,6 and8 , theadjustable guide member 52 is a one-piece, unitary member that is made of a resilient plate such as a spring metal plate. Theadjustable guide member 52 is bent such that theadjustable guide member 52 has anattachment part 52a, aninclined part 52b, a mainchain contact part 52c and afront guide part 52d. Theattachment part 52a constitutes a first part that is fixed to thesecond guide plate 42 by a pair offasteners 58 such as rivets. Of course, theattachment part 52a can be fixed to thesecond guide plate 42 using other fixing means such as by bond or welding. In any case, theparts adjustable guide member 52. The cantilevered part (i.e., theparts inner surface 42a of thesecond guide plate 42. Theattachment part 52a is fixed to thesecond guide plate 42 at a location that is closer to a chain enter side of thechain receiving slot 48 with respect to a front most free end of the cantilevered part (i.e., theparts adjustable guide member 52 is a resilient plate that is flexed to vary the width of thechain receiving slot 48. - In the illustrated embodiment, the
second guide plate 42 is a one-piece, unitary member, as best seen inFigures 9 and 10 . Thesecond guide plate 42 is typically made of a rigid metal plate that is bent and shaped to form an outside portion of thechain receiving slot 48. The thickness of thesecond guide plate 42 is larger than the thickness of theadjustable guide member 52 such that thesecond guide plate 42 is more rigid than theadjustable guide member 52. However, since theattachment part 52a is fixed to thesecond guide plate 42 and the mainchain contact part 52c is supported by theadjustment member 54, theadjustable guide member 52 does not flex during normal operation of thefront derailleur 12. During downshifting of a chain from thelarger chain ring 18 to thesmaller chain ring 20, the mainchain contact part 52c of theadjustable guide member 52 contacts the chain to move it laterally towards thebase member 26. Thus, the minimum effective width of thechain receiving slot 48 is between the firstinner surface 41 a and the mainchain contact part 52c of theadjustable guide member 52. - In understanding the scope of the present invention, the term "comprising" and its derivatives, as used herein, are intended to be open ended terms that specify the presence of the stated features, elements, components, groups, integers, and/or steps, but do not exclude the presence of other unstated features, elements, components, groups, integers and/or steps.
